摘要: The present invention relates generally to the use of polyaryletherketone-based thermoplastic materials in the fabrication of logging tools employed in high pressure, high temperature, downhole logging applications. A polyaryletherketone resin bonded with glass fibers is formed into a housing for the logging tool. The housing is constructed by any of the following processes: filament winding or compression molding. When used with a logging tool, the housing encloses the operative components of the logging tool, such as sensors and sources, and protects the operative components from borehole fluids.

摘要: Polyetherimide oligomers having crosslinking end cap moieties which provide improved solvent-resistance to cured composites are generally represented by the formula: ##STR1## wherein X=--O-- or --S--; ##STR2## n=1 or 2; ##STR3## E=allyl or methallyl; R=a trivalent C.sub.(6-13) aromatic organic radical;R.sub.1 =any of lower alkyl, lower alkoxy, aryl, or substituted aryl;R'=a divalent C.sub.(6-30) aromatic organic radical;j=0, 1, or 2; andG=--CH.sub.2 --, --O--, --S--, or --SO.sub.2 --Blends generally comprise substantially equimolar amounts of the oligomers and a comparable, compatible, noncrosslinking, etherimide polymer of substantially the same backbone. The crosslinkable oligomers are made by reacting substituted phthalic anhydrides with hydroxyaryl amines and suitable crosslinking end cap reactants, or by self-condensation of phthalimide salts followed by capping the polymers. Related polyetherimides of the present invention can be prepared by the condensation of nitrophthalic anhydride, diamines, dialcohols (dihydricphenols), and phenolic, crosslinking end caps (A--OH), or the condensation of bis(phenates) or dialcohols (bisphenols), diamines, nitrophthalic anhydride, and amine-terminated end caps (A--NH.sub.2) or nitro-terminated end caps (A--NO.sub.2).The oligomers and blends can be prepregged, and can be cured to form advanced composites having aerospace applications.
